Description

Connector and connector assembly Technical Field The present invention relates to a connector, and more particularly, to a connector that is connected to a connection object by pressing the connection object in a predetermined pressing direction. The present invention also relates to a connector assembly including such a connector and a connection object. Background As such a connector, for example, patent document 1 discloses a connector 3 in which a plurality of conductive probes 2 are held in a housing 1 as shown in fig. 27. Each probe 2 has a first plunger 2A and a second plunger 2B that are urged in opposite directions to each other by an internal spring. By disposing the connector 3 between the interposer 4 and the substrate 5 and pressing the substrate 5 toward the interposer 4 in opposition, the tip of each first plunger 2A elastically contacts the terminal of the wiring layer 4A of the interposer 4, whereby the first plunger 2A is electrically connected to the terminal of the wiring layer 4A, and the tip of each second plunger 2B elastically contacts the terminal of the wiring layer 5A of the substrate 5, whereby the second plunger 2B is electrically connected to the terminal of the wiring layer 5A. Thus, the plurality of terminals of the wiring layer 5A of the substrate 5 are connected to the plurality of terminals of the wiring layer 4A of the interposer 4 via the plurality of probes 2, respectively. In this way, the first plungers 2A of the probes 2 connected to the terminals of the wiring layer 4A of the interposer 4 are connected to the corresponding bump electrodes 6A of the chip substrate 6 via the interposer 4. Prior art literature Patent literature Patent document 1 Japanese patent laid-open No. 2024-35498 Since the first plunger 2A and the second plunger 2B of each probe 2 are elastically movable in the pressing direction of the interposer 4 and the substrate 5, even when positional displacement occurs in the pressing direction between the plurality of terminals of the wiring layer 4A of the interposer 4 and the plurality of terminals of the wiring layer 5A of the plurality of probes 2 and the substrate 5 due to manufacturing tolerances or the like, the positional displacement can be absorbed and an electrically connected state can be ensured. However, if there is a positional shift along the surface direction of the wiring layers 4A, 5A orthogonal to the pressing direction between the plurality of terminals of the wiring layer 4A of the interposer 4, the plurality of probes 2, and the plurality of terminals of the wiring layer 5A of the substrate 5, the positional shift is difficult to be absorbed, and there is a possibility that the reliability of the electrical connection may be impaired. Disclosure of Invention The present invention has been made to solve the above-described conventional problems, and an object of the present invention is to provide a connector capable of ensuring reliability of electrical connection even if a positional shift occurs in a direction orthogonal to a pressing direction of a connection object. The present invention also provides a connector assembly including such a connector and a connection object. The connector according to the present invention is a connector for connecting an object to be connected by pressing the object to be connected in a predetermined pressing direction, the connector including: a case formed of an insulating material and having a front surface facing the direction of the connection object; an electroconductive contact held in the housing and extending in the pressing direction, and A retainer formed of an insulating material and held to the housing so as to cover a front surface of the housing, The contact includes a movable portion which is elastically displaceable in a pressing direction with respect to the housing and at least a part of which protrudes from the retainer toward the connection object, The movable part has: A distal end portion facing the object to be connected along the pressing direction; A first connection part configured at the front end part; A first extension portion extending from the first connection portion in a direction opposite to the front end portion along the pressing direction and having a first width in an orthogonal direction orthogonal to the pressing direction, and A second extension portion extending from the first extension portion in a direction opposite to the front end portion in the pressing direction and having a second width wider than the first width in an orthogonal direction, The positioner has a movable portion insertion hole through which the second extension portion of the movable portion can be inserted, When the connection object is pressed against the connector, the opposite side contact of the connection object is brought into contact with the first connection portion and pressed in the pressing direction, the movable portion is elastically displaced in the direction opposit
